According to the verdict, the man must have exploited a young woman close to him, born in 2000 since she was 7-8 years old.
The story behind the many years of abuse was revealed when the 52-year-old's cohabitant in mid-October this year received back a mobile phone that the young woman had borrowed from her.
The district court found the 52-year-old guilty of child rape, rape, sexual harassment and minor drug offenses.
In addition to the prison sentence, he must pay SEK 330,000 in damages to the vulnerable woman.
The 52-year-old believes that he is innocent and admits only minor drug offenses.
